TRACTOR DESIGN ANALYSIS AND RESEARCH BASED ON KANO- AHP MODEL AND JACK

In order to make the tractor better meet the needs of users under the premise of satisfying the use of functions, the Kano- AHP model is used to design the appearance of the tractor. Firstly, the emotional needs of users are collected, and the tractor modeling is designed according to the requirements combined with the Kano model. The design scheme is displayed through Rhino in the form of three-dimensional modeling. According to the design requirement index was summarized by Kano model, the tractor modeling hierarchical structure model was established by using analytic hierarchy process, the weights of each index were obtained, and the best design scheme was selected according to the weights. Finally, the selected best scheme was imported into Jack ergonomics simulation software for stress analysis and comfort analysis of the lower back, and the analysis results were used to check whether the scheme met the man-machine physiological standards.
